In each figure, components having the same reference numeral have approximately the same function, and duplicate explanation may be omitted. In FIG. 1, first, a portion similar to the conventional example will be described. This open-type rotating electric machine has a structure in which a rotor 3 which is arranged inside a stator 2 which is fixed to a frame 1 with a gap and a shaft 4 which fixes the rotor 3 are supported through a bearing 5. Frame 1
A bracket 6 attached to the rotor 3, a blade 7 provided at an axial end portion of the rotor 3, an air guide 8 having an end portion close to the axial end portion of the blade 7, and an air guide 8 of the air guide 8.
